      Pros

      Slack is fully invested in building a supportive workplace for anyone who is ready for their next challenge. As I'm returning to management after a long hiatus doing IC work, I've taken advantage of the chance to refresh my skills. My direct supervisor is a fantastic mentor, Slack is a truly transparent workplace, and the Learning & Development team offers a terrific and evolving curriculum to support leaders at every skill level. You really can do the best work of your life at Slack, which is incredibly rewarding.

      Cons

      Slack is a fast-growing company. That's exciting, but some teams are still polishing the rough edges off the internal services they provide.

      Hyper growth company with great people

      Pros

      I have worked at many start ups and this is the most exciting, dynamic, and professional start up environment I've worked in. The people here are mature, bright, empathetic, and collaborative. The company is growing unbelievably fast, but everyone is still very helpful and team oriented. There is a big focus on diversity and inclusion, which is so important and appreciated. You can really feel how big of an opportunity there is here and for those who like building something great, there will be a ton of room for growth.

      Cons

      This is a high growth environment so employees needs to be ok with being flexible and creating the play book as we create a fairly new market. This is not a con, just a note on who will succeed here.
